The Department of Conservation has won the inaugural Supreme New Zealand Biosecurity Award for its great white butterfly eradication project.
Primary Industries Minister Nathan Guy announced the awards, which will be an annual event, and said the department's project was the first time anywhere in the world that an unwanted butterfly population had been eradicated.
In 2013, the department offered a bounty of $10 for each great white butterfly caught in the Nelson region during the school holidays.
DoC rangers carried out more than 263,000 searches in the region for the butterfly and its eggs, caterpillars and pupae.
The Industry Award went to Biosecurity Excellence at Port of Tauranga.
